grep from filename.txt can't get the whole line!


I've made a script to grep a file

for i in `cat filename.txt`
    strings ./binfile | grep "$i" 2>&1 > /dev/null

this works fine as long as in filename.txt i don't have any entries with spaces. But in my case i want to grep something with spaces like "lala tata"
and the above script greps for lala and then with tata.

When I use while read i have the same problem.
any ideas anyone??

You have to set IFS to a newline character before executing your loop:

for ...; do ...; done

Or, for a nicer single line version:
for ...; do ...; done

also " tr " could delete END OF THE LINE , try

echo abcd | tr -d '\n'
